Filed: 1993-06-21
Abstract: The invention relates to a non-linear optically active polyurethane comprising a polymeric main chain and a donor-.pi.-acceptor sidegroup, with the sidegroup comprising a rigid donor group which is also part of the polymeric main chain. By incorporating rigid donor groups into the non-linear optically active polyurethane a high glass transition temperature (Tg above 170 ·C) is obtained, and hence increased thermal stability. The invention further relates to non-linear optically active polyurethanes having a Tg above 170 ·C, and to non-linear optically active waveguides comprising non-linear optically active polyurethanes according to the invention. Suitable rigid donor groups include nitrogen- or sulphur-containing alicyclic groups. In particular, dihydroxy pyrrolidine groups in which the nitrogen atom is directly coupled to the .pi.-acceptor group and dithiafulvene groups were found to be highly suitable for obtaining non-linear optically active polyurethanes of good thermal stability and polarizability.

Title: Process for Applying Chemical Papermaking Additives from a Thin Film to Tissue Paper
Inventor: AMPULSKI ROBERT S
IPC: D21H21/18
Filed: 1993-08-20
Abstract: Disclosed is a process for making soft tissue paper which includes providing a dry tissue web and then applying a sufficient amount of a chemical papermaking additive from a thin film to the dry web. The chemical papermaking additives are added to the surface of the tissue paper to enhance properties of the paper such as strength, softener, absorbency, and/or aesthetics. The chemical papermaking additive application process includes the steps of diluting the chemical papermaking additive with a suitable solvent, applying the diluted chemical solution to a heated transfer surface, evaporating the solvent from the dilute solution to form a film, and then transferring the film to the tissue by contacting the dry tissue web with the heated transfer surface. Preferably, the tissue web is dried to a moisture level below its equilibrium moisture content before application of the papermaking additive.

Title: Iron and driver golf club design
Inventor: MATTHEWS ROBERT T
IPC: A63B53/04
Filed: 1995-04-19
Abstract: A golf club comprises an elongated shaft;  an iron or driver club head including:  a lofted club face; and, a short, offsetting hosel that interconnects the shaft with the club head.  The elongated shaft has a longitudinally extending centre-line axis.  The shaft is interconnected in offset club-face-leading relation to the club head,  through the offsetting hosel, so that the centre-line axis is aligned in generally centred, intersecting relation with the sweet-spot on the club face.  It is characteristic of these clubs that with the shaft laid out on a flat, level  reference surface with the club head extending in otherwise unsupported relateion over the edge of that surface, the natural balance of  the  club rotates  the club head so that  the  face thereof  then positions itself upwardly in a generally level orientation, as measured at right angles to the loft of the club face.

Title: Load-transfer equipment (spreader) for various types of transport unit
Inventor: MENDE BURKHARD
IPC: B66C1/28
Filed: 1994-10-26

Title: Vacuum cleaner with accessory shutoff
Inventor: JACOBS SCOTT
IPC: A47L5/32
Filed: 1995-05-04
Abstract: A socket is provided on the upright portion of a vacuum cleaner for the insertion of the wand on the distal end of the accessory hose.  The wand, which is normally inserted into the socket when the accessories are not being used, engages a linkage mechanism within the socket.  The linkage mechanism closes a valve door within the suction stream when the wand is removed to close the suction passageway from the vacuum source to the base and open the suction passageway to the hose.  The linkage mechanism opens the valve door when the wand is replaced to close the suction passageway to the hose and open the suction passageway to the base.   The present invention automatically closes the suction passage from the floor engaging portion whenever the accessories are being used and assures that the suction connections are always in the proper position for floor cleaning or above-floor cleaning.

Patent CA-2153641-A1 (CA)
Title: Digital communications system and method
Inventor: GIBBARD MARK R
IPC: H04L27/01
Filed: 1995-07-11
Abstract: An equalization scheme for digital transmissions across a time dispersive radio channel, h(D), is described which reduces the computational complexity required at the portable receiver. The scheme utilizes a decision-feedback equalizer (DFE) at the base-station to equalize transmissions from the portable and a Tomlinson-Harishima (TH) precoder with forward filter to pre-equalize transmissions from the base-station. No equalizer filters are required at the portable unit, giving a reduction in hardware complexity at that terminal. Transmissions to and from the portable unit are time division duplexed on the same carrier frequency. A data sequence is transmitted from the portable to the base station which is used to either estimate the channel impulse response or optimize a DFE. The coefficients of the DFE are then used directly to characterize the TH precoder and forward filter or, alternatively, the coefficients to the TH precoder and DFE can be calculated fro the channel estimate. Data that is pre-equalized by this structure will have a reduced amount of ISI when received at the portable unit. The system is retrained within the coherence time of the channel or, alternatively, a channel estimator or the DFE can be used to track the channel, with regular updating of the pre-equalizer parameters.
Patent CA-2157913-A1 (CA)
Title: Method and device for measuring the position and orientation of objects in the presence of interfering metals
Inventor: ELHARDT SCOTT T
IPC: F41G3/22
Filed: 1994-06-24
Abstract: A method of measuring the position and orientation of an object is disclosed in conjunction with an apparatus to achieve this method. The method and apparatus reduce the metal effects caused by metal objects which are in close proximity to a magnetic field generator. The metal effects are reduced by utilizing a magnetic field generator which creates a rotating magnetic field vector and then measuring the time required for that magnetic field vector to travel between a known reference point and the sensor whose position is being measured. By keeping the frequency of the rotating magnetic field vector constant and measuring the time required for this magnetic field vector to travel the previously distance, an angle between a reference axis and a vector directed toward the sensor can be determined. Once appropriate angles are measured, calculation can be undergone to determine the position of the sensor. Furthermore, by utilizing a plurality of sensors the orientation of the sensors with respect to one another can be determined.
